SLAVE I/O INPUT (TB5)
SLAVE I/O
Input/Output terminals are used to control a second gate operator in a
Master/Slave system.
ADJUSTMENTS
REVERSE
Adjustable pot controls gate sensitivity to blockages by the instantaneous
RIGHT (R61)
rise in motor current. When the limit exceeded, the gate reverses a
programmed distance and stops. If Max Retry Count is enabled, the gate
waits a programmed pause time, then tries to resume. The gate will retry
twice before faulting out.
REVERSE
Adjustable pot controls gate sensitivity to blockages by the instantaneous
LEFT (R160)
rise in motor current. When the limit exceeded, the gate reverses a
programmed distance and stops. If Max Retry Count is enabled, the gate
waits a programmed pause time, then tries to resume. The gate will retry
twice before faulting out.
NOTE:
LiftMaster gate operators have two reverse sense adjustments (left and right)
where other gate operators have only one. This allows greater flexibility of
installation. For instance, you can install a gate on an incline and not worry
about sacrificing downhill gate sensitivity.
INRUSH
Adjustable pot controls the delay in sensitivity to a Reverse Sense input.
(R203)
This delay in sensitivity prevents the initial motor inrush current from causing
a fault condition. The weight of the gate determines this setting.
